Bacterial cells are often surrounded by several layers which are collectively called the cell envelope.

细菌通常被几层包围，统称为细胞包膜。

Now bacterial cells are often surrounded by several layers which are collectively called the cell envelope.

细菌外表通常分为数层，它们统称为细胞包膜。

Cable bacteria are able to perform this amazing feat using a series of parallel fibers, sandwiched between the cell membrane and the cell envelope.

电缆细菌可以使用夹在细胞膜和细胞膜之间的一系列平行纤维来完成这一惊人的壮举。

After that it's ready to be translated into viral proteins, wrapped in the cell's lipid envelope, and sent out of the cell as a newly made virus.

之后，它就可以转录成病毒蛋白，包裹在细胞的脂质包膜中并作为新产生的病毒从细胞中排出。
